VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 416,5;74, dated December 3, 1889.

' Application filed February 8,

To all whom t may concern:

Be it known that I, FRANK P. CRosBY, re-

siding at Chicago, Illinois, have invented cer-` the line 4 4 of Fig. l, eXcept that the mixing` tube is shown in elevation. Fig. 5 is a transverse section of the jet-pipe, taken through the jet-orifice in the line 5 of Fig 1; and Fig.

G is a plan view of a damper for regulating the flame of the vapor-burner.

In making my improved vapor-burner I use a spreading-plate A, intended to spread or distribute the iiame of the burning vapor. I carry a pipe B from any desired source or supply of oil intended to be vaporized, and preferably'arrange this pipe as shown in Fig. 2, leading back and forth over the spreadingplate, so that -it will become heated, and thereby heat the oil flowing through the same. I prefer to elevate this supply-pipe slightly above the spreading-plate, so as to leave an air-,space between it and the spreading-plate, as shown in Fig. l, and to that end I prefer to provide the spreading-plate with upwardlyprojecting ridges or lugs adapted to hold the supplypipe a proper distance above the saine. The supply-pipe may, however, if preferred, lie directly on the spreading-plate, although, as vabove stated, I prefer to elevate it somewhat above it, as it would not be so liable to be burned out and destroyed by the,

heat. Y

- The supply-pipe is provided with a standpipe or downward extension C, that extends down through the spreading-plate, which is furnished with a proper hole or opening to.

permit it to be arranged therein. At the lower end of the stand-pipe I arrange one or more jet-pipes D, which are intended to be carriedout from the stand-pipe, preferably on each side, although in some applicat-ions of the vapor-burner it will be found desira- 1889'. SerialNo.299.208. (Nomodel.)

ble to carry it out on but one side, and in other cases it will be found desirable to use severalbranches extending in different directions, the obj ect in all cases being to adapt the jet-pipe in form and position to the particular place of use. This jet-pipe is intended to be provided with one or more jet-orifices, through which the vapor may pass to the place where it is burned. As shown in Fig. 5, the jet-orifices are formed in a conical shape inclining from the inside of the pipe to its outer edge. In order to make the oriiice of this shape, a hole can be bored in the opposite side of the pipe to permit the jetoriiices to be formed. This hole can be stopped by a plug, as shown in Fig. 5. By having the orice thus formed small at the outer edge of the pipe and of increasing size to the inside of the pipe its capacity may be easily enlarged by iiling off the outer edge of the pipe immediately over the opening. .Of course the size of the jet-orifice will be increased as the thickness of the pipe at that point is diminished. In this way we can se- Below the jet-pipe is arranged a drip-panl Einto which the oil which overflows at the jet-orifices before the fire is lighted will be caught. This drip-pan, thus catching the overflowing oil, affords an easy means of lighting the fire, as all that is necessary to start the tire will be to apply a lighted match to the oil in the drip-pan.- The oil thus igniting and burning will heat the jet-pipe, the stand-pipe, and the spreading-plate, and thus cause the incoming oil to be vaporized, so that instead of oil vapor will issue from the jet-orifices. This drip-pan is preferably suspended or held in place by means of ears or lugs c, embracing the drip-pipe and attached thereto by means of screws, as shown in Figs. I and 4, although other means of holding it in place may be employed, vif desired.

Immediately above the jetoriiices I arrange mixing-tubes F. (Shown in the drawings.) These mixing-tubes are preferably of an enlarged diameter at their lower ends, so

IOO

as to catch the Vapor escaping from the jetoritices. They may be described as somewhat of a bell or dome shape. They are. preferably mounted on the stand-pipe and made adjustable up and down thereon. To thus mount them and hold them in place, I employ a horizontal bar G, preferably arranged with round ends fitting into a socket g, cast or otherwise attached to the mixing-tubes. This horizontal bar is also preferably arranged to be adjusted up and down on the stand-pipe by means of a set-screw H. This will enable the lower or enlarged ends of the mixing-tubes co-be adjusted at a proper distance from the jet-orifices, so as to catch the vapor escaping therefrom. At the same time a space should be left between the lowerends of the mixing-tubes and the jet-orifices to .enable iair to be drawn into `the lower ends of .the .mixing-tubes to hecomemixed with the vapor ,from the orifices. The upper ends of the mixing-tubes are preferably connected togetherbymeansof a yoke I, provided with au elongated slot or opening around the stan d-pipe.

At the outer sides of the mixing-tubes are preferably arranged square or angular projectionsf, adapted to receivea wrench or'lrey to enable the mixing-tubes to be adjusted at an angle forward or backward. To permit thisradjustrnent is theobject of employing an elongated opening or slot `in the yokefsurrounding the stand-pipe.

By adjusting the mixing-,tubes at .an anglel forward or backward the ilame from the burn-` in g vapor may be directed against the forwarder against the rear side of the spreading-plate, as may be desirable from time to time, or by leaving them in a vertical position the iiame and heat .will be directed against the central portion of 1the spreadingplate.

To apply the key or wrench to the purpose of adjusting the position of the mixing-tubes, the door of the stove, when a stove is used, as shown in Fig. 4, may be opened-and the adjustment made. It will be obvious that the lower mouth of the mixing-tubes must be wider than the range of movement of that mouth in the adjustment described, so that the iiuid discharged through the jet-orifice shall Abe received by the mixing-tube at whatever position the latter may be placed within the possible range of its adjustment. 4It is obvious, also, that in order that the deilection ot the flame, which is the purpose of i the Hue. XVhile I have shown this damper in `one of the rear lids of the stove, yet it is obvious that it may be made independent of the lid and arranged in any proper position in the top of the stove or even at its sides, the objeetpbeing to permit an access of air back of the vapor-burner to cause the flame to be drawn back through the stove toward the flue. I have found by practical experience that this damper not only secures the results above explained, but that it also prevents noise from the burning vapor.

In operation the oil is admitted into the supply-pipefromthe reservoir in which it is kept by means of a cock or valve that will permit the proper amount to constantly flow into the supply-pipe. After traversing the supply-pipeovertlie spreadin g-plate it, passes down through the st-and-pipeandinto the jetpipe. `Elowing along thejet-,pipe it reaches the orifices and `overflows into ,the drip-pan. When lighted in the drip-pan, as above lexplained, the jet-pipe and other parts 4are so heated that the oil is converted into vapor and issues inthe form of .vapor from the jet orifices. It thenpasses up, together with the air .whichbecoines mingled with it, into =the mixing-tubes, and j emerges at the top, ,where it is burned immediately beneath thespreading-plate. This operation will continueas long as oil ,is admitted 4through ythe supply pipe.

`I have described my improvement in vapor-burners in connection with a ycookingstove, as shown in 4, although -it is obvious that it may `be employed in ether kinds of stoves, in steam-generators, water-heaters,

and in various other places and for various other uses. I do not mean,therefore, to confine myself in the use ot' my improvements to a cooking-stove alone, but intend to employ them for all uses to which they are adapted.

What l regard new, and desire tosecure by Letters Patent, is-

1. In ra vapor-burner, the combination of a supply-pipe, onc o r more jet-orifice pipesrhaving o ne or more,jetoriiceaone or more mixing-tubes arranged over the jet orifice or orijices and vuninclosed at the upperend underneath the spreading-plate, and said spreading-plate, whereby an intense fiame is generated under and spread by saidplate, causing the latter to become intensely hea-ted, the supply-pipe being located on top 0f thespreadingplate very near thereto, but separated therefrom by aslight interval, whereby the presence ot' the intensely-heated spreading-plate reliably heats thesupply-pipe, and the interval betweensaid spreading-plate and supplypipe prevents overheating of the latter, substautially as setforth.

2. In a `vapor-burner, thecombinat-ion of a supply-pipe, one or more jet-orifice pipes having one or more jet-orifices, oneor more mixing-tubes arranged over the jet orifice or ori- Iices and uninclosed at the upper end, and a IOO IIO

spreading-plate located above the mixing tube or tubes, one of said last-mentioned parts being supported and movable up and down on a standard which is fixed with respect to the other, substantially as set forth. A

3. In a vapor-burner, the combination of a supply-pipe, one or more jet-orifice pipes having one or more jet-orifices, one or more mixing-tubes arranged over the jet orice or oritices and uninclosed at the upper end, aspreadingplate located above the mixing tube or tubes, horizontal pivots on which the mixing tube or tubes are supported and adapted to be rockedback and forth, the lower open end of the mixing tube or tubes being wider than the range of the rocking movement of such lower end, and the spreading-plate being wider than the range of movement of the upper end, whereby the jet of vapor discharged into the mixing-tube may be deflected in passing therethrough to vary the point and angle of its impact against the spreading-plate, substantially as set forth.

4. In a vapor-burner, the combination of a supply-pipe, one or more jet-orifice pipes having one or more jet-orifices, one or more mixing-tubes arranged over the jet orifice or oriices, a spreading-plate located above the mixing tube or tubes, and a drip-pan located below the jet-orifice pipe or pipes substantially parallel and opposite to the spreading-plate, a slight space being left between the jet-orifice pipe or pipes and the drip-pan, whereby the heated currents generated atthe under surface of the spreading-plate are refiected back and forth between the spreading-plate and the drip-pan and circulated between such pan and the jet-orifice pipes, substantially as set fort-h.

5. In a vapor-burner, the combination of a supply-pipe, one or more jet-orifice pipes hav- FRANK P. CROSBY. 1
